FABRICATION OF THIN WALLED SHAPED CHARGE LINERS BY POWDER METALLURGY

Abstract

A unique powder metallurgy method was developed for producing dimensionally acceptable high density shaped charge liners from copper powders for the M28A2 rocket. The problems involved in tool design and processing of this thin walled cone are discussed. A number of cones were produced to the specified dimensions from various commercial copper powders. A powder with good flow characteristics appeared to be the main requirement. This insured a uniform fill of powder in the die cavity, provided good dimensional control and minimum density variation in the cone. The best combination of properties was obtained on cones produced from copper powders containing approximately 40 to 60% fines (-325 mesh) and sintered at 1650 F. The average density of the finished cone was 8.4 gm/cc, which is 94% of the theoretical density of Cu. Typical tensile properties of these cones were 30,400 psi tensile strength and 31% elongation.
